A sputtering apparatus for depositing layers of material onto a substrate includes a vacuum chamber, a first target and a second target positioned within the vacuum chamber. A source of power is placed in electrical communication with the first target and the second target. A switch alternately connects the source of power between the first target and the second target. The first target and the second target are different materials. The switch connects power to the first target when the transport mechanism positions the substrate near the first target and the switch connects power to the second target when the transport mechanism positions the substrate closer to the second target.
